Onyx's isolator rings measure pressure on slurries, wastewater and sludge; its pinch valves serve as final control elements for slurry, wastewater, sludge, and dry bulk materials; the duckbill check valves combine high capacity with low head loss; and its double-door check valves serve as check valves with a rubber hinge.
